During takeoff roll left outboard tire blew and then left inboard tire blew seconds later. Copilot was in left seat flying and due to excessive pull to left used too much right brake and both right tires blew. Aircraft, even using maximum reverse thrust, left end of runway rolling about 10-12 KTS and came to rest 60' past overrun in grass. Brake material was found in left flap. Left outboard gear door was damaged. None of the 7 passenger were hurt. Gross weight was approximately 20100 pounds this aircraft did not have the 1A mod that beefed up the brake-tire system. After replacing wheels and tires aircraft was ferried to stateside maintenance. Callback conversation with reporter revealed the following information: original certification of aircraft required 45 min wait on turn around. Manufacturer beefed up lead fuse plugs which release air from tire when it heats so it will not blow, to eliminate wait time. This aircraft equipped with these plugs, so no wait time required. No previous problems with this plane. There is a modification available to put larger brakes and larger wheels to further mitigate overheat problem but the cost of $85,000 is considered prohibitive.
Original NASA ASRS Text
Title: TIRES BLEW, BRAKE SHATTERED ON TKOF ROLL.
Narrative: DURING TKOF ROLL LEFT OUTBOARD TIRE BLEW AND THEN LEFT INBOARD TIRE BLEW SECONDS LATER. COPLT WAS IN LEFT SEAT FLYING AND DUE TO EXCESSIVE PULL TO LEFT USED TOO MUCH RIGHT BRAKE AND BOTH RIGHT TIRES BLEW. ACFT, EVEN USING MAX REVERSE THRUST, LEFT END OF RWY ROLLING ABOUT 10-12 KTS AND CAME TO REST 60' PAST OVERRUN IN GRASS. BRAKE MATERIAL WAS FOUND IN LEFT FLAP. LEFT OUTBOARD GEAR DOOR WAS DAMAGED. NONE OF THE 7 PAX WERE HURT. GROSS WT WAS APPROX 20100 LBS THIS ACFT DID NOT HAVE THE 1A MOD THAT BEEFED UP THE BRAKE-TIRE SYSTEM. AFTER REPLACING WHEELS AND TIRES ACFT WAS FERRIED TO STATESIDE MAINT. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING INFORMATION: ORIGINAL CERTIFICATION OF ACFT REQUIRED 45 MIN WAIT ON TURN AROUND. MANUFACTURER BEEFED UP LEAD FUSE PLUGS WHICH RELEASE AIR FROM TIRE WHEN IT HEATS SO IT WILL NOT BLOW, TO ELIMINATE WAIT TIME. THIS ACFT EQUIPPED WITH THESE PLUGS, SO NO WAIT TIME REQUIRED. NO PREVIOUS PROBLEMS WITH THIS PLANE. THERE IS A MODIFICATION AVAILABLE TO PUT LARGER BRAKES AND LARGER WHEELS TO FURTHER MITIGATE OVERHEAT PROBLEM BUT THE COST OF $85,000 IS CONSIDERED PROHIBITIVE.
